Area of a Rectangle: A = lw

  • l is length
  • w is width

Step-by-step explanation:

Step 1: Define

A = 1650 yd²

l = 55 yd

w = unknown

Step 2: Solve for w

  1. Substitute in variables [Area of a Rectangle]:                                              1650 yd² = (55 yd)(w yd)
  2. [Division Property of Equality] Divide 55 yd on both sides:                        30 yd = w
  3. Rewrite:                                                                                                           w = 30 yd
